An apparatus for aerosol collection and fluid analysis includes a rotary motor, an aerosol-collection disk configured for mounting on the rotary motor, and a fluid-analysis disk that is also configured for mounting on the rotary motor. The aerosol-collection disk includes at least one interior inlet, at least one peripheral outlet and a passage coupling the interior inlet with the peripheral outlet, and a particle collector opposite the peripheral outlet. The fluid-analysis disk includes at least one fluid in each of a first reservoir and in a second reservoir on or in the fluid-analysis disk and offset from a central axis of the disk, wherein each reservoir has an outlet and a stopper in the outlet of each reservoir to seal the reservoirs; and release of the fluids from the reservoirs is spin-induced. |

1. An apparatus for aerosol collection and fluid analysis, comprising:
a rotary motor including a stage configured for rotation; an aerosol-collection disk including at least one interior inlet, at least one peripheral outlet and a passage coupling the interior inlet with the peripheral outlet, and a particle collector opposite the peripheral outlet, wherein the collection disk is configured for mounting on the stage of the rotary motor for rotation thereon; a fluid-analysis disk configured for mounting on the stage of the rotary motor for rotation thereon, the fluid-analysis disk comprising at least one fluid in each of a first reservoir and a second reservoir on or in the fluid-analysis disk and offset from a central axis of the fluid-analysis disk, wherein each reservoir has an outlet and a stopper in the outlet of each reservoir to seal the reservoirs, wherein selection between release of fluids from the first and second reservoirs is determined by the rate of rotation of the fluid-analysis disk or by acceleration in the rate of rotation of the fluid-analysis disk, wherein the fluid-analysis disk is configured to release the fluid from the first reservoir when the fluid-analysis disk reaches a first rotation or rotation-acceleration rate, wherein the fluid-analysis disk is configured to release the fluid from the second reservoir when the fluid-analysis disk reaches a second rotation or rotation-acceleration rate distinct from the first rotation or rotation-acceleration rate, and wherein the fluid-analysis disk is characterized by at least one of the following:
a) the outlet of the first reservoir faces a first direction relative to the central axis, and the outlet of the second reservoir faces a second direction relative to the central axis, wherein the second direction differs from the first direction;b) the first reservoir is offset from the central axis of the fluid-analysis disk by a first radius, wherein the second reservoir is offset from the central axis of the fluid-analysis disk by a second radius that is less than the first radius; andc) the first stopper in the first reservoir has a first release or sealing force, and the second stopper in the second reservoir has a second release or sealing force, wherein the first release or sealing force is less than the second release or sealing force. |
